Subject: [PATCH 6/8] ARM: mvebu: enable SDHCI card detection using DAT3 pin on A388-GP

The newest revisions of A388-GP (v1.5 and higher) support only
DAT3-based card detection, which is enabled by this commit. Hitherto
revisions, without such modification, will be impacted with a broken
card detection - in order to operate the cards have to be present
during kernel boot.
